Thermal Analysis of Helical Gear Box Model PE - 50

Abstract

The model PE-50 is a product of ELECON Engineering Co. Ltd. PE- 50 is a four stage Gear Box with helical Gears. As the main problem of a gear industry is dissipation the heat generated inside the gear box, for this purpose Thermal analysis is required. Objective of present study is determination of thermal rating and power losses of the gear box and determination of temperature distribution of gear box casing. The tool used for this purpose are Pro/ENGINEER Wildfire 2.0 for solid modeling and ANSYS-10.0 for analysis.

Thermal Analysis of gearbox is carried out in Software ANSYS with transient and steady-state module and the temperature distribution along whole gear box is observed. During the operation of gear box, rise in temperature of lubricating oil due to total power losses inside the gear box is obvious. Heat from lubricating oil is transferred to the casing. Temperature at selected points on the casing is measured after eight hours running of the gear box. With this as input, cooling

pattern is observed on ANSYS after two hours interval of time.
